It seems, that after the last U2 update of cups, there are random printer queue hangs. Also jobs remains in the printer queue in the Samba. I have to clean Samba queue and restart cups daemon to make it work again (I still don't know what steps are exactly needed to make it work so I'm providing almost all what I did): lpc status rm /var/spool/samba/* rm /var/cache/samba/printing/* /etc/init.d/cups restart cupsdisable MYPRINTER (see output of lpc status) cupsenable MYPRINTER I'm not really sure if this is Samba or cups issue. Any comments?
It seems that downgrading to the previous cups-1.1.22-0.rc1.9.7 solve this problem. Current cups-1.1.22-0.rc1.9.8 has been issued by RHSA-2005:772-8 and closed STR #1068 (bug #164642), bug #164641 and STR #1042 (bug #168072). So one of these fixes probably caused unusability of the printing subsystem via Samba in RHEL4 (U2). The problem could be reproduced by setting up a printer, run Samba and try to print few documents (there Win XP from Word, Outlook, Excel etc). At some point, the jobs remains in the queue and the printer stops to print (we have network printers HP4000, HP4300 and Minolta 2300). The older version of the cups and cups-libs could be found in the RHN by searching for cups package in the dialog just under the menu.
I'm confirming that after downgrade to cups-1.1.22-0.rc1.9.7 (see comment #3) the printing subsystem works Ok again. I have three Samba shared printers which we use regullary everyday, so after 2 weeks it seems to be proved that the latest errata caused troubles with printing.
Changing component to the cups.
Milan: you have added your comment to a report of a (seemingly) different bug, and it makes the report very confusing. Please file a separate bug report.
